Maximize z = 6XI + 2x2 + 4x3, using the "Simplex Method" the entering variable will be X3. O False True If S1, S2, & S3 have respective ratios of 1.5, 1, & 3, the leaving variable using the "Simplex Method" will be S2. * False True If the reduced costs of all the empty cells in the transportation problem are either negative or zero, the solution is then optimal. True False A "destination" represents the location to which commodities are distributed or delivered. * False True - + Z = 1400 - 3DI + D2 this suggests that a unit change in the capacity of the first constraint (DI = +1 min) increases the value of z by $3. = * Z True False
